The objective of this study was to create a tool that will enable renewable energy microgrid (REμG) facility users to make informed decisions on the utilization of electrical power output from a building integrated REμG connected to a smart grid. A decision support tool for renewable energy microgrids (DSTREM) capable of predicting photovoltaic array and wind turbine power outputs was developed. The tool simulated users’ daily electricity consumption costs, avoided CO2 emissions and incurred monetary income relative to the usage of the building integrated REμG connected to the national electricity smart grid. DSTREM forecasted climate variables, which were used …
Modelling Methane Production Kinetics Of Complex Poultry Slaughterhouse Wastes Using Sigmoidal Growth Functions, Niamh Power, Aidan Ware
Modelling Methane Production Kinetics Of Complex Poultry Slaughterhouse Wastes Using Sigmoidal Growth Functions, Niamh Power, Aidan Ware
Publications
The kinetic evaluation of the methane potential from poultry slaughterhouse waste streams was performed using modified sigmoidal bacterial growth curve equations (Richards, logistic, Gompertz) in order to investigate their suitability to describe the degradation patterns associated with complex substrates, primarily composed of fats. The methane potential and degradation patterns under mesophilic conditions were assessed using Biochemical Methane Potential (BMP) assays. A nonlinear least-square regression analysis was performed to fit the sigmoidal functions to the cumulative methane production curves with respect to time generated from the BMP assays. In the cases modelled the Gompertz and logistic, three parameter models, sufficiently …
Supplying Bio-Compressed Natural Gas To The Transport Industry In Ireland: Is The Current Regulatory Framework Facilitating Or Hindering Development?, Niamh Power, Daniel Goulding, Dan Fitzpatrick, Rodger O'Connor, James D. Browne
Supplying Bio-Compressed Natural Gas To The Transport Industry In Ireland: Is The Current Regulatory Framework Facilitating Or Hindering Development?, Niamh Power, Daniel Goulding, Dan Fitzpatrick, Rodger O'Connor, James D. Browne

Compressed Natural Gas (CNG) and biomethane when blended as a transport fuel (bio-CNG) have significant potential in Europe. However, this alternative fuel has not been developed in several European countries. One of the barriers to market penetration is the absence of a coherent regulatory framework to eliminate the disparity between European and national legislation. Using Ireland as a test case, this paper examines how conflicting policies can be aligned to ensure effective bio-CNG market development. A key barrier is the regulatory ambiguity placed on transport fuel suppliers and investors who wish to connect to the network to supply bio-CNG. For …
